Background Heat is one of the most important physical harmful factors in many work environments. Due to the nature of work, bakery activity is considered as one of the high-risk occupations in terms of heat stress. Therefore, the aim of this study was evaluated of heat exposure in bakery workers using WBGT, HSI and UTCI indices. Methods This study is a descriptive-analytical cross-sectional ...

Background and aims: Health hazards under heat stress conditions are well known and many industrial workers expose to heat stressful environments. Protection of the health of workers with suitable productivity is very important the idea requires adoption of a heat stress index that is both reliable and easy to use. Recent studies have found that Thermal Work Limit (TWL) performs better than W...

Heat-stress-related injuries and deaths are a serious concern to the military. A joint Army/Air Force publication (TB MED 507) provides heat stress guidance based on the wet-bulb globe temperature (WBGT), soldier work rate, and clothing level. In a military environment, however, accurate WBGT measurements or predictions (for planning purposes) may not be available or practical to obtain; thus, ...

Background and purpose: Heat is a common type of energy that is produced during industrial processes in many work places. Workers who are working in hot areas may be exposed to heat stress. The aim of this study is to evaluate the effect of a designed cool spot on reduction of Mean Radiation Temperature (MRT) and Wet Bulb Glob Temperature index (WBGT) on a group of furnace workers. Materia...
